Patent DE-2845930-A1 (DE)
Title: Frequency control of asynchronous generator - has turbine driven asynchronous machine, rotor phase current is controlled, so that power passes via converter-network path
Inventor: NACHTIGAL JOACHIM ING GRAD
IPC: H02P9/00
Filed: 1978-10-21
Abstract: The arrangement is designed to convert kinetic energy into electrical energy. The asynchronous machine, whose stator is connected to a constant frequency network, is driven by a turbine. The machine rotor is connected through a static convertor to the same network as the stator. Convertor frequency is so changed, that the sum of the frequency impressed on the rotor and the frequency proportional to the rotor variable speed is always equal to the network frequency. Rotor current phase is so controlled, that when its speed is above the synchronous speed, rotor power is delivered through the convertor to the network. when the speed drops below, the network (1) supplies the rotor power through the convertor. The reactive load or the rotor fed asynchronous machine (3, 4) can be adjusted using a regulator, which varies the amount of rotor current, such that the reactive laod i.e. the voltage or the asynchronous machine, corresp. to the network (1) requirement, is regulated independently from the 'effective' output.

Title: Peak voltage detector for periodic voltages relating to film speed - has trigger clocking two flip=flops that drive input switching transistors and has bipolar output transistors
Inventor: ROSSBACH HORST
IPC: G01R19/04
Filed: 1978-12-28
Abstract: The peak voltage detector can be realised as an integrated circuit by avoiding the need for large capacitors. The rectified signal(B) describing film speed is passed via two diodes(D1, D3) and two alternately conducting FET switches(T1, T4) to the bases fo two bipolar transistors(T3, T6). The rectified speed signal is also applied to a threshold trigger switch(SS1) whose output controls an inverter(T7). The trigger output and the inverter output produce two sequences of clock pulses for two flip-flops(FF1, FF2). The outputs of the flip-flops control the FETs which in turn control the bipolar transistors connected to the output(9). A second pair of FETs(T2, T5) earth the bases of the bipolar transistors and are also controlled by the flip-flops. The output is a sequence of state changes with each transition occurring at a peak in the input speed signal.

Title: Clamp for multiple plug connectors - has common clamping rail whose pressure is exerted by spring adjustable by set screw
Inventor: SCHLEGEL FRIEDRICH
IPC: H01R13/518
Filed: 1979-01-04
Abstract: The application is to multiple multiway plug and socket assemblies, as used in data processing equipment. The connector comprises a series of in line sockets (17), fixed in the base of the equipment, with which individual loose plugs (18) connect. The plugs are secured in position by a clamping rail (20) which is acted on by a spring (25) to give a positive pressure on the plug. The pressure is set by a screw, located in the equipment housing, which bears against the spring. In a typical arrangement the clamping rail has a series of lugs arranged so that a lug bears against each end of a connector plug. The arrangement is easy to install and allows ready access to the connectors. It also withstands the forces which may be applied to the connectors by cables and conductors, thus providing a required tension relief.
